Abstract
Feedback from a power monitor sampling a portion of the output beam of an optical resonator is used to control the position of a pump beam relative to a second laser. The pump beam position or orientation is adjusted in response to a dither signal imposed on the position or tilt of an external optic or mirror in order to maximize the efficiency of the second laser in converting pump power to output power. Feedback based on the response of the power monitor is used to control the position or tilt of the mirror or optic to which the dither was applied.
